During a 1981 marketing dispute, the PGA Tour briefly used the name TPA Tour.
TPA stood for “Tournament Players Association.” The change followed a dispute between the tour organization and the PGA of America over marketing and commercial control. By that point, touring professionals had operated separately from the PGA of America since their 1968 organizational split, but the relationship over names and branding remained contentious.
The rebrand was announced in late August 1981, so the 1981 season is sometimes described as the TPA Tour season. “TPA Tour” was not the name of a new rival circuit, nor was it a permanent replacement for the PGA Tour. It was the tour’s official name during a short transitional period.
The disagreement was resolved in less than seven months. In March 1982, the organization changed its name back to PGA Tour, which is why historical references may show both names for the same 1981–82 episode. The stored answer is therefore the single standard answer to this question.
